Question

10a+2b=4&15a-5b=-2 solve this equation by eliminating method

Answer 1

$\bold{\huge{Answer:}}$



Equation:-

10a+2b=4
15a-5b=-2

Solving By Elimination method!!!!!


10a+2b=4×15

15a-5b=-2×10


___________

150a+30b=60

150a-50b=-20
___________
80b=80

b=80/80


b=1

==============================
Define Another Equation!

Substitute the value of y in another equation!!!

10a+2b=4

10a+2(1)=4

10a+2=4

10a=4-2

10a=2

a=2/10

a=1/5


$\bold{\huge{Conclusion:}}$


a=1/5

b=1


Thanks!!!
